Let this be a lesson to cellphone users everywhere: Look both ways before making that call.

A West Philly man chatting on his phone failed to do so yesterday while crossing the street at Conshohocken Avenue and Cranston Road about 4:15 p.m. and was struck by a SEPTA bus, police said.

The 20-year-old was taken to Temple University Hospital in stable condition, and an officer at the hospital said he suffered no broken bones or major injuries.

At the scene, passengers on the route 40 bus were placed on a replacement vehicle, and service was resumed shortly after the crash.

Given his condition, the victim likely will be released from the hospital early this morning, the officer on-hand said.
